Sternohyoid Muscle Disorders

The sternohyoid muscle is one of the small but important muscles in the neck that helps control the movement of the hyoid bone, a structure that plays a role in swallowing and speaking. Although disorders specifically affecting this muscle are uncommon, similar muscle problems in the neck can cause pain and limit movement. This guide provides evidence-based details in plain English about the anatomy of the sternohyoid muscle, what can go wrong with it, the possible causes and symptoms, how it is diagnosed, treatment options, prevention tips, and when you should consult a doctor.

Anatomy of the Sternohyoid Muscle

Understanding the anatomy of the sternohyoid muscle can help you appreciate how disorders affect its function.

Structure & Location

• Structure: The sternohyoid is a slender, flat muscle.

• Location: It is found in the front of the neck, below the hyoid bone, and is one of the infrahyoid muscles (muscles located beneath the hyoid bone).

Origin and Insertion

• Origin: The muscle originates from the manubrium of the sternum (the upper part of the breastbone).

• Insertion: It attaches to the lower part of the hyoid bone.

Blood Supply

• Arterial Supply: Blood is supplied by small branches from the inferior thyroid artery and other nearby vessels.

• Importance: Good blood supply is necessary for the muscle to receive oxygen and nutrients, which is essential for its function and repair.

Nerve Supply

• Innervation: The muscle receives nerve signals from the ansa cervicalis, a loop of nerves in the neck.

• Role: These signals control the muscle’s contraction and coordination with other neck muscles.

Key Functions

1. Depressing the Hyoid Bone: Helps lower the hyoid bone during swallowing.

2. Stabilizing the Hyoid: Assists in maintaining the position of the hyoid bone during speech and swallowing.

3. Facilitating Swallowing: Works in harmony with other neck muscles to ensure safe and effective swallowing.

4. Supporting Neck Movements: Contributes to the stability and movement of the neck.

5. Assisting Breathing: Plays a minor role in maintaining airway patency by helping adjust neck position.

6. Coordinating with Other Muscles: Works with muscles like the sternothyroid to provide smooth and coordinated movement during daily activities.

Types of Sternohyoid Muscle Disorders

While sternohyoid-specific problems are rare, disorders of the muscle and nearby structures can include:

• Muscle Strain: Overstretching or tearing of the muscle fibers.

• Muscle Spasm: Involuntary contractions that cause pain.

• Myofascial Pain Syndrome: Chronic pain that originates from trigger points within the muscle.

• Tendonitis: Inflammation where the muscle attaches to bone.

• Neuromuscular Disorders: Conditions where nerve signals to the muscle are disrupted, leading to weakness or dysfunction.

• Fibromyalgia: A widespread pain condition that may affect the neck muscles.

• Traumatic Injury: Direct trauma or injury to the neck can damage the sternohyoid muscle.

• Degenerative Changes: Age-related degeneration can affect muscle strength and function.

• Post-Surgical Scar Tissue: Surgery in the neck region can lead to scar formation affecting the muscle.

• Inflammatory Myopathies: Disorders where the body’s immune system attacks muscle tissue.
